' lie it known that LI'IERMAN L. VAGNERL a citizen of-the United-States, residing in, Mount Vernon, in the county of VVestchester and State of New York have invented certain new and useful Improvements in'lf-ype following isa specification.

This invention relates to the main frames; paper carriages and case-shift, mechanisms" of typewriting machines, particularly those ofthe front strike class,

"to 'the wellknonni Underwood writing max chine.

machine's having extra 1widecarr1a'ges,1'an

and more' especially There is. frequent demand for typewriting in manufacturing the Underwood machines heretofore, it has'been the'practice tobnild t l1e' mai n frame for either "an ordinary carriage or an extra. wide carriage, .=as-.the case might be, This 'j involves-the necessity; of two stocks of-main fra'r'nes, and inakesit impossible-to change-a wide car riage machine to. an ordinary carriage ma chine -or vice versa'.

The principal object of my invention is to make it practicable to use the same main' frame for either wide-or ordinary carriages.

sothat only a single stock of main frames need be manufactured. and carried, and so that the machine may at any time be readily changedfroin an ordinary carriage .to a wide carriage machine.

In carrying out 'my invention, I provide interchangeable short.and long front rails .and supports; -interchangeableshort and long rear mails and supports, and interchangeableshift rails, andI also make certain changes in the wide carriages to adapt them to"the interchanging system.

The ordinary or short carriages are usually provided each with a sin le front roll.

1 upon llllWidB' or rail-at the rearof the long carriage. order to-prevent tipping up of either end of the long carriage,;1'prov1dewheels-at the rear thereof'to run upon the under side' of the rear rail, these wheels at such intervals that at least two are always Working. Each. of the long; and

short front rails'is mounted uponystandards, which have similar feet or bases to be' secured ,upon seats provided uponthe main frame. I The shortlrear rail bearings on which short carriage and a long inade'tubular or hollow,

sections that will slip-ortelcscope upon the short-rail, so that in changing from ashort .front rail, rear rail and shift rail,

' isof the usual cylindrical type and engaged by the usual. eyes fonl the carriage. This rear rail, however; "is mounted upon "detachable blocks andjthe'lattercarry a long rockin frame which carries the column 'stops' of the, 'usiialtabulating mechanism. The blocks and platem'frame are detachable to- 'sgether "from the mainframe and interchan eablewith alon'gbot'tom rail or ball track or a long. carr1age .-Isaid.track having ears or is hinged the long frame. carrying along'co'lumn-stop bar. v

.I provide a short .pl'aten-shift railfor the shift rail for the wide carriagef Prefera and is divided into carriage tojawide carriage it is only neces- 'sary to slipthese sections upon the shift rail, without other change in the platen-shifting mechanism..

The entire'system f'main frameand jinterchangeable parts is such that main frames containingcomplements of type systems and .otherlmechanism, jnay he made upand car- 1 'ied"in stock, and either long or short carriages maybe iitted thereto as required; or changes from long to short carriages or vice versa may be made at any time after the ma chine is delivered to. the typewriter sales establishment or to a-customer.

The main frame comprisesa rectangular base 1, front and rear corner-posts 2, 3, and upper framework 1:, all usually cast inone iecei A platen 5 is usually mounted upon a shiftin frame 6 having a roll 7 to run upon a shift rail 8', said shifting frame being mounted upon a carriage 9 having ears 10 to slide upon a rear rail 11. The carriagealso has a front bar- 12 having a roll 13 to run upon a front rail 1 f. Said front railis secured by nuts 15 in a pair of standards 16, 17 having bases 18, 19, detachably secured by screws 20 upon plate-like seats 21, 22 formed or provided upon the front upper portion of the machine frame. Said standards or supports 16, 17 are secured together by means of said rail and said nuts 15, and also by means of a rod 23 and nuts 24, said rod having teeth 25, for the usual margin gage, and carrying a'rocking frame 26 for'the usual line-locking tappet 27', said rockin frame having an .arm 28 passing down t rpugh an a erture 29 in the base 18 to o erate the be l-striking arm 30. Secure upon the standards 16, 17 is also a front scale bar 31 for the usual carriage and margingage indexes.

The rear rail 11 is of the usual construction, so that no change may be made in the manufacture of the ordinary or short carears 32 upon blocks 33, the latter held by screws 34 upon the rear sides of lugs 35 cast upon the rear'of the main frame; said lugs formed-with seats 36 for the blocks 33, and

the cars 32 having tongue-and-groove joints 37 with the blocks 33 and secured thereto by screws. 38.

Secured-by screws 39 in the lower por tionsof the. blocks 33 are opposite pintles 40 upon which is hinged a rocking frame 41 to. carry the usuabcolumn sto s of the tabulating mechanism. Except f dr its length, this .nocltingframe is similar to the Said rail is mounted by means of.

and a long presently be described. The frontrail 47."

long rocking frame hereinafter described. The screws 34 may be loosened and the blocks 33 taken off, together with the raili- 11 and the rocking frame 41; and said long rockingframe may then occupy" the space taken up by) the removed blocks, it being too longto confined between the lugs 35. to the rear of which'said blocks were secured. When the short front and longrails are removed, the frame has the appearance seen at Fi 7, the front seats havingthreaded ho es 42 for the screws- 20',-and

also holes 43 to. receive dowel pins 44,- Fig, 6.

As seen at Fig. 20, the long carriage 315 has a roll 16 to run along the front'rail 47, a roll 48 to .run upon the long shift rail 49, rear guiding track, which will is secured by; nuts 50 upon standardsjl carried upon outer ends of arms 52 project ing oppositely from the main frame-'and having bases or plates 53 provided--with dowels 54 to cured by means 55 up0n the seats 21, 22, Said standards 51 are also connected by a scale bar 56, a margin gage rod 57 and a rod 58, which carriesa hinged rack -59 ofthe bell-ringing and line -locking mechanism, anal-m 60 depending from said hinged rack corresponding to said arm 28. I

The wide carriage is guided by means of upper and lower ball tracks 60, I 61, the former secured or formed upon the rear fit in the holes 13, andalso. see-- bar of the carriage, and the lower-attached bv screws 62, Fig. 22, to the ln 35, the

latter having in theirtop forwar portions seats (33 for said track or rail 61. Balls 6%, running in grooves 65in said tracks,- are connected by a spacer bar 66, which is formed midway of its ends with incisions G7,- 68, and bent to form an opening 69, Fig.

15, in which is rigidly held an arbor'70,'

upon the projecting end of which turns a pinion 71-nieshing-with upper and lower racks 72, 73, the former. upon the traveling track 60 and the latter upon the stationary track 61, whereby the balls Mare controlled.

From the front side of the track wade;

pend three ears 74 carrying rolls 75- torun them are constantly running upon said, track, so that ne1ther.end'of the carriage can he accidentally tipped up or depressed.

From the rear; side of the lower rail depend cars 76 carrying pintl es 77, uppn the under side of the track 61. One

which is hinged 'a'swinging frame c'ompr1s-'v ing end bars 78, a rock shaft 79, a rod 80 12 and a rack bar 81. Column stops 82 are supported upon the rod 80. and engage the teeth of the rack bar. This-swinging frame, it will be understood, is much longer than -thc swinging frame 41, at Fig. 5, and occupies the room formerly taken up by the detached blocks V I To remove the long carriage it is only necessary to take out the screw (32 and to catch hooks 83 over pins S-l, Fig. 11, whereby the tracks 60, 61 are held together, against relative movement, and hence loss of the balls (34;

is avoided. The upper track (50 is secured by means of screws 85 to lugs 86 formed upon the rear bar ST of the long carria e, Fig. 11, For the long carriage is provided a: long shift rail 88, which is forme'din two sections joining at 89, said sections being hollow to telescope upon the short rail 8, each section being longitudinally slitted at 90 to clear the thin plate-like flanges 91, upon which the rail 8 is fixed, Figs. 8 and 17, said flanges being formed upon a rocking frame 9 comprising a rock shaft 93 journal ed upon the main frame. Depending from the under side of the sections of the shift rail 88 are Wide flanges or braces 94 having overlapping tongues secured together byscrews 9t). Screws 9? also secure the sections'of the rail 88 to the supporting rail 8.

When it is desired to change from a wide carriage to a short one, it is only necessary to take off the sections of the rail SS, and exchange the front and rear long rails for front and rear short rails and appurtenances, and

mount the short carriage on them in the usual manner; and the operation may be reersed for changing from a short carriage to a wide carriage.

Variations may be resorted to within the scope of the invention, and portions of theimprovements may be used without others.
